The question of fluctuating blood pressure is interesting. A personâs blood pressure does fluctuate during the day depending on your activity level. During exercise the blood pressure may rise as high as 230 mm on the systolic and 100-110 mm on the diastolic. However, this will return to the normal range as soon as the exercise stops. And while you are asleep, the blood pressure may go lower than normal, which is normal.
1 Itâs also normal for readings taken once a day or once a week (at the same time) to vary by around 20. 2  However, with variable blood pressure, the readings taken once a day or once a week are likely to vary by 50 or more. 3  People with variable blood pressure show wide fluctuations daily, weekly and monthly.f a personâs blood pressure varies greatly during monthly readings at the doctorâs â say 130/80 one month, then 170/90 the next â it is also likely to vary greatly week by week, day by day, hour by hour, even minute by minute.
